Abstract
Procédé de floculation et de déshydratation d'une suspension aqueuse composée de solides en suspension, ce qui consiste à introduire dans la suspension : (a) une solution polymère concentrée et (b) une solution polymère diluée. Ce procédé est caractérisé par le fait qu'on introduit les solutions polymères concentrée et diluée dans le substrat pratiquement simultanément. On introduit, de préférence, les solutions polymères concentrée et diluée dans la suspension sous forme de composition aqueuse comprenant une solution aqueuse diluée de polymère et une solution concentrée de polymère. Ce procédé apporte des améliorations en ce qui concerne la filtration et les solides en pain.
